R: Text Representations of R Objects

dump {base}

R Documentation

Text Representations of R Objects

Description

This function takes a vector of names of R objects and produces text representations of the objects on a file or connection. A dump file can be sourced into another R (or S) session.

Usage

dump(list, file="dumpdata.R", append=FALSE)

Arguments

list

character. The names of one or more R objects to be dumped.

file

either a character string naming a file or a connection. "" indicates output to the console.

append

if TRUE, output will be appended to file; otherwise, it will overwrite the contents of file.

Details

At present the implementation of dump is very incomplete and it really only works for functions and simple vectors.

dump will warn if fewer characters were written to a file than expected, which may indicate a full or corrupt file system.

The function save is designed to be used for transporting R data between machines.

Examples

x <- 1; y <- 1:10
dump(ls(patt='^[xyz]'), "xyz.Rdmped")
unlink("xyz.Rdmped")
